Season 17's Bachelor Sean Lowe and his wife and winner Catherine Giudici have welcomed their first child.

The couple, who first met on the popular ABC show and got engaged after Sean gave Catherine the final rose, first announced the pregnancy late last year and their son, Samuel Thomas Lowe, was born on Saturday (July 2).

Continuing with their decision to document the pregnancy on social media, Catherine stayed true to form and hilariously tweeted "'It is time.' - Rafaki", shortly before going into hospital on Friday.

The pair also shared the first photos of their son on social media on Sunday, and while Sean opted to post the simple caption of "my boy and me", Catherine continued to affirm her newfound love for her child with an adorable picture.
